采用一步溶液合成法制备了异金属配合物[(In Cl)4(Me OH)2(m-OMe)4(μ3-OMe)2(μ3-SCH2CH2SCH2CH2S)2(Cu PPh3)2(]1),并通过单晶X-射线衍射分析对其进行表征。该配合物晶体属于正交晶系,空间群为Pna21,其中a=23.921 4(7),b=10.449 6(3),c=26.687 0(8)?,V=6 670.9(3)?3,Z=4,Mr=1 807.56,Dc=1.800 g/cμ3,m(Mo Ka)=2.429 mm-1,F(000)=3 584,S=0.969,最后修正I>2s(I)的8 279个可观察点和717个参数,得到修正因子R1=0.049 6和权重因子w R2=0.077 0。在配合物1中,每个铟(In)原子通过2个μ3-OMe和4个m2-OMe构成以铟(In)原子中心的平面桥式连接,在每个单胞中有四个铟(In)原子可归属为(In4)四核,并且2个[Cu(PPh23)]+离子碎片通过[SCH2CH2SCH2CH2S]-配体连接In4核,从而形成了标题的三元配合物。
The metal complex [(In Cl) 4 (Me OH) 2 (m-OMe) 4 (μ3-OMe) 2 (μ3- SCH2CH2SCH2CH2S) 2 (Cu PPh3) 2 (1) was prepared by one-step solution synthesis. And characterized by single crystal X-ray diffraction analysis. The crystal of the complex belongs to the orthorhombic system with the space group Pna21, where a = 23.921 4 (7), b = 10.449 6 (3), c = 26.687 0 (8) (I), Z = 4, Mr = 1 807.56, Dc = 1.800 g / cμ3, Mo Ka = 2.429 mm -1, F 000 = 3 584 and S 0.969. 279 observable points and 717 parameters, resulting in a correction factor R1 = 0.049 6 and a weight factor w R2 = 0.077 0. In complex 1, each indium (In) atom constitutes a planar bridged connection centered at the indium (In) atom by 2 μ3-OMe and 4 m2-OMe, with four indium In) atoms can be assigned to (In4) tetranuclear, and two [Cu (PPh23)] + ion fragments connect to In4 core via [SCH2CH2SCH2CH2S] - ligand to form the title ternary complex.
